Abstract

The automotive industry has a high demand for reliable simulation methods capable of tackling the complex turbulent air flow around vehicles. The Ahmed reference model is a generic car-type bluff body with a slant back. It is frequently used as a benchmark test case for this kind of flow. In spite of the relatively simple geometry of the Ahmed body, the flow around it retains some main features of the flow around real cars.
